The 911 GT3 RS, one of Porsche’s most popular, coveted and successful track-inspired production cars, has been given a final, thrilling injection of thoroughbred motorsport technology resulting in the Porsche 911 GT3 RS 4.0. Limited to 600 vehicles worldwide, the 911 GT3 RS 4.0 brings together in a sports car the attributes that have made the Porsche 911 GT3 a consistent winner on the race track.
The motorsport-derived 4.0-liter engine, already the highest displacement 911 engine ever, also features the highest per-liter output – 125 horsepower (hp) per liter – from a naturally aspirated Porsche flat-six engine. The engine uses forged pistons, the connecting rods are fashioned from titanium, and the crankshaft has been lifted unchanged from the 911 GT3 RSR race car. It achieves its maximum power of 500 hp at 8,250 rpm. Maximum torque of 339 ft/lbs (460 Nm) is reached at 5,750 rpm.
The Porsche 911 GT3 RS 4.0 offers truly impressive performance, lapping the famed Nürburgring-Nordschleife in 7 minutes and 27 seconds. Available exclusively with a six-speed manual transmission, the Porsche 911 GT3 RS 4.0 sprints from 0 to 60 mph in only 3.8 seconds (0-100 km/h in 3.9 s), and with its gearing designed for the race circuit it reaches the 124 mph (200 km/h) mark on the race track in under 12 seconds.
The Porsche 911 GT3 RS 4.0’s outstanding driving dynamics come from numerous, meticulously coordinated details. In addition to using suspension components typically encountered in motor racing, weight reduction is also of supreme importance. Equipped as standard with lightweight components such as light but strong carbon fiber sport bucket seats, carbon fiber front fenders and luggage compartment lid, and weight-optimized carpets, the two-seater’s ready-for-action weight is just 2,998 lbs (1,360 kg) with a full fuel tank. The Porsche 911 GT3 RS 4.0’s power-to-weight ratio is 5.99 lbs/hp (368 hp/tonne).
This limited edition 911 is painted Carrara White as standard and emphasizes its proximity to motor racing by its dynamic appearance. Signature characteristics are the wide track, the low vehicle position, the large rear wing with side plates, central twin tailpipe, and the aerodynamically optimized body. Air deflection vanes mounted on either side of the front bumper – called ‘flics’ or dive planes – make their first appearance on a production Porsche. They create increased downforce on the front axle, and together with the steeply inclined rear wing, provide aerodynamics on par with its performance capabilities. As a result, at the 193 mph (311 km/h) top track speed, aerodynamic forces exert an additional 426 lbs (190 kg) of downforce, thus pushing the Porsche 911 GT3 RS 4.0 onto the road.
With a manufacturer’s suggested retail price starting at $185,000 (excluding destination), the new Porsche 911 GT3 RS 4.0 goes on sale in the United States in late 2011.
